Hi there,

I have a requirement to trigger a business process with a parameter value from an anonymous web service and get errors while publishing the code in the Creatio environment. Below I have mentioned the complete code of the web service and the error screenshot of the error.

Note: I have pre-created the business process with the parameter and written the web service.

I referred other community articles such as 

https://community.creatio.com/articles/web-service-without-authorizatio…

https://community.creatio.com/questions/calling-business-process-parame…

These codes currently seem to be outdated and not working in the Atlas version of creatio. Please give me suggestions to resolve this issue.

Code :
